Type declarations and associated basic functions for PSCI.

Documentation

data PSCiConfig

The PSCI configuration.

These configuration values do not change during execution.

Constructors

PSCiConfig

Fields

• psciLoadedFiles :: [FilePath]
• psciEnvironment :: Environment

Instances

Show PSCiConfig

Methods

showsPrec :: Int -> PSCiConfig -> ShowS

show :: PSCiConfig -> String

showList :: [PSCiConfig] -> ShowS

data PSCiState

The PSCI state.

Holds a list of imported modules, loaded files, and partial let bindings. The let bindings are partial, because it makes more sense to apply the binding to the final evaluated expression.

Constructors

PSCiState

Fields

• psciImportedModules :: [ImportedModule]
• psciLetBindings :: [Declaration]
• psciLoadedExterns :: [(Module, ExternsFile)]

Instances

Show PSCiState

Methods

showsPrec :: Int -> PSCiState -> ShowS

show :: PSCiState -> String

showList :: [PSCiState] -> ShowS

initialPSCiState :: PSCiState

type ImportedModule = (ModuleName, ImportDeclarationType, Maybe ModuleName)

All of the data that is contained by an ImportDeclaration in the AST. That is:

• A module name, the name of the module which is being imported
• An ImportDeclarationType which specifies whether there is an explicit import list, a hiding list, or neither.
• If the module is imported qualified, its qualified name in the importing module. Otherwise, Nothing.

psciImportedModuleNames :: PSCiState -> [ModuleName]

allImportsOf :: Module -> PSCiState -> [ImportedModule]

State helpers

updateImportedModules :: ([ImportedModule] -> [ImportedModule]) -> PSCiState -> PSCiState

Updates the imported modules in the state record.

updateLoadedExterns :: ([(Module, ExternsFile)] -> [(Module, ExternsFile)]) -> PSCiState -> PSCiState

Updates the loaded externs files in the state record.

updateLets :: ([Declaration] -> [Declaration]) -> PSCiState -> PSCiState

Updates the let bindings in the state record.
